And now, after rebooting, again no connection,nothing happening after sudo /sbin/dhcpcd eth0,but connection did came back after sudo /etc/rc.d/rc.inet1 start.Strange, every time it's different..Well... as long as it comes back, I'm happy

Well,... very strange things are happening now..One would think that there can be a hardware problem, but I have been running U-lite on this machine for a long time, and never there has been a problem with internet connection. Not once.Now I wanted to test this again with a live cd (Damn Small), like you suggested, but the machine doesn't want to boot from the cd drive any more...It always comes up with VL!I checked the boot sequence setup, but cd drive is still the first...And after booting, VL has sometimes internet connection, and sometimes not...?!?
